I have a Bushnell Trophy cam and so far I'm impressed with it. I'm a pretty new owner myself, and my camera has only been out in the woods a short time. However it seems to be fast and take good pictures. I have it set on a trail, and have caught animals running through the area on it. I have it set to take three pics when activated, and usually a get at least two or running game. I even caught a spike shedding an antler recently. Battery life was still full last I checked, and it had been out in temperatures into the teens for a couple of weeks. I think it had taken 387 pictures last time, so I would rate battery life as excellent. The night time pictures are a little grainy but I could still make out details pretty well, and it isn't really a big deal(at least to me)Now my biggest gripe about the unit, the bear box (made by bushnell) is a very poorly executed design. You can't use lag bolts to secure it to a tree, you must use screws or a python cable lock. If you decide to get a bear box for it don't get the bushnell.

Amazon has them for $130 right now.

I have had good luck with Moultrie. They aren't the smallest but they have performed well and at a decent price in my opinion.
It makes a lot of difference how you set them up. Pay careful attention to the sun direction as it really can wash out pics and fool with the triggering.
We had a great time with the pics of bears coming in to our bait this fall. The cameras are a fun addition to your hunting gear. I don't take them too seriously but it is nice to check out pics. We have one really neat set of a deer cruising through and minutes later here come the wolves. I think you will enjoy your purchase. Have also heard good things about the Bushnells but don't own one myself.

I have 4 Wildgame Innovation cameras. couldn't be happier with them. They take great still and video images though some pics are a little blurry if they are running. The IR is great on both models i have.
